P0420 code even with an O2 spacer. What next?
**edit** Sorry, it is definately the P0420 code, not P0128. I guess you cannot edit the actual post name?
Hi guys,
I have an 2003 S40 with 130k miles. It has had the P0420 CEL code since I've had it. If I reset the code it always came back within a day.
I read about the O2 sensor spacers for the rear sensor and decided to give one a try. I'm still getting the code, although now when i reset it it takes about a week for it to come back.
Is there anything else I can check/do to try and get rid of this code? Not wanting to do anything $$$ like replacing the cat...
Also I did not buy the IPD CEL Boss, I used a cheap one from eBay. From the pictures it looks like IPD's is a bit longer than the one I have. Could that be the problem, the sensor not being pulled far enough out of the exhaust stream?
Thanks,

I may break down and buy IPD's... But first I'm going to try making a little tent of thick aluminum foil with a few little holes poked in it to cover the sensor head
I realize it's just a fix to cover the real problem of a cat that is not performing 100%. But I am not prepared to spend alot money on an old car just to get the cat back up to Volvo's specs.
Thanks for the advice!

Oh wow. I have to say Kentucky was quite insane when it came to vehicles in the mid-90's. When I moved to Louisville I first got hit with a sales tax on a 10 year old vehicle. I had to prove I paid sales tax to Florida where I bought my truck 10 years before. Then they hit me with a tax on my truck's insurance premium. And it all had to be paid at once. Next was the smog check. Holy taxes Batman. Kentucky taxed everything and often. I could not move fast enough out of that craziness.
